Needle Size Chart
The right needle size and point type for your fabric, at a glance.
| Fabric | Needle size (US/EU) | Point type |
|---|---|---|
| Sheer, chiffon, voile | 60/8 – 65/9 | Sharp/Microtex |
| Quilting cotton, lightweight wovens | 70/10 – 75/11 | Universal |
| Medium wovens (shirting, poplin) | 80/12 | Universal |
| Knits, jersey, interlock | 70/10 – 90/14 | Ballpoint/Jersey |
| Stretch knits with spandex | 75/11 – 90/14 | Stretch |
| Denim, canvas, twill | 90/14 – 100/16 | Denim (sharp, reinforced shaft) |
| Heavy upholstery, multiple layers | 100/16 – 110/18 | Denim or Universal (heavy) |
| Leather, vinyl, faux leather | 90/14 – 100/16 | Leather (wedge point) |
| Topstitching, heavy topstitching thread | 90/14 – 100/16 | Topstitch (large eye) |
Reading needle size numbers
Needle sizes are listed as two numbers, like 80/12 — the first is the European metric size (needle shaft diameter in hundredths of a millimeter), the second is the American/Singer numbering system. A higher number in either system means a thicker needle.
Point type matters as much as size
A sharp point pierces woven fabric threads cleanly, which is what you want on wovens but is exactly what causes skipped stitches or small holes on knits. A ballpoint or stretch needle instead pushes knit fibers aside rather than piercing them, preventing runs and dropped stitches. Using a sharp needle on a knit is one of the most common causes of a wavy, skipped-stitch seam.
Change your needle more often than you think
A needle dulls after roughly one project's worth of sewing (some quilters use "one bobbin" as their rule of thumb), and a dull or slightly bent needle causes problems — skipped stitches, popping sounds, snags — that look like a machine or tension issue but resolve immediately with a fresh needle.
